INHALER.

SPECIFICATION forming part of Letters Patent No. 577,674, dated February23, 1897.

Application filed June 1, 1896. Serial No. 593,781. [No model.)

To aZZ whom it may concern:

Be it known that I, THEODORE B. WILCOX, a citizen of the UnitedStates,'residing at Newark, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in Inhalers;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it ap- 1o pertains to make and use the same.

The present invention relates to improvements in inhalers belonging tothat class which is adapted to hold menthol or some other aromatic ormedicinal substance or compound in the form of a stick, disk, candle, or

the like, the object of these improvements being to secure a tight jointbetween the different parts of the inhaler (and so to prevent theevaporation and escape of the menthol or other substance) and to adaptthe device for use both as an inhaler and as a friction appliancewithout the removal of a cap or any other part of the device. Thedifficulty with other inhalers of this sort has been that the 2 5 cap orother detachable part was likely to become lost or mislaid, therebycausing inconvenience, or that in case there were no detachable part theflexible joint employed was liable to make an imperfect seal for the in-3o haler and permit the escape of the volatilized substance or compound.

I accomplish the results aimed at by my present invention by means of avery simple means of union between the two movable,

3 5 but not detachable,'parts of my inhaler. The

arrangement is clearly shown in the accompanying drawings, in which-Figure 1 is a side elevation of my inhaler. Fig. 2 is a verticalcross-section thereof, and

40 Fig. 3 is a detail view,

In the drawings, A represents my inhaler as a whole, the same being madeup of an exterior part B and an interior part 0. The latter part 0 isstamped in the process of man- 5 ufacture so as to have the projectingjournals 0 c at precisely opposite points, as shown. The outer part B issimilarly stamped by means of a slightly-larger die, the object being toform boxes I) b for the journals 0 c.

The journals 0 c and the boxes I) b are formed just midway of the widthof each of the parts concerned, and when they are sprung together, withthe journals arranged Within the boxes, the two parts B and O are unitedby a pivot-joint, as will be clearly understood.

Within the interior part 0 is set a box D, the bottom of which strikesagainst the curved inner sides of the part 0, while the top thereof isflush with the top of said part 0. The boX D is intended for holding thestick, disk, or candle E of menthol or other aromatic or medicinalsubstance.

As shown in Fig. 1, the

ner end.

The screw H passes through a screw threaded nut I, which is soldered tothe inside of the part B in such a position as to receive the screw.

The screw H is passed through the nut from below before being secured byany suitable means to the cap F.

It is evident that the cap cannot be wholly removed by reason of theenlargement h upon the inner end of the screw H.

The cap can,

however, be raised by turning the screw in the proper direction untilthe enlargement h binds against the nut I.

The screw H passes through an opening considerably larger than itself,so that there is an annular opening around the screw for the passage ofair.

Moreover, the nut I is cut away at i "i, the cuts being deep enough toallow the annular passage before referred to tocommunicate with theinner chamber B of the part B.

When the cap is screwed down, there is no possibility of the vaporsescaping from the chamber B in that direction,the cap making a perfectseal with the flattened end of the neck Gr.

Moreover, I find that in practice I can construct the two parts to fiteach other so nicely at the journals and also at the contaoting edgeseverywhere that there is no escape of vapor at any point when the cap isdown.

This result is assisted by the employment of the journal and boxarrangement deable stop or detent for limiting the relative scribed inthe foregoing specification. movement of the parts in one direction, as
